Prevents the target from switching out.

Octolock stops the target from switching out or fleeing as long as the user remains in battle.
Pokémon can still switch out with its own effects such as:

• using a move that switches the user out (such as U-Turn or Baton Pass).
• if it is holding a Shed Shell or Smoke Ball
• the held Eject Button is activated.
• the Trainer uses an escape item such as Poké Doll
• if the target faints and the player is able to switch out the current Pokémon while playing in shift mode.

At the end of each turn, the target's Defense and Special Defense is lowered by one stage.
Stats can be lowered to a minimum of -6 stages.

• In
  BDSP
  and Gen 9 this move can not be selected in battle.
